2 men killed, 1 woman injured in Colorado Walmart shooting

THORNTON, Colo. - Two men were killed and a woman was injured in a shooting inside a suburban Denver Walmart on Wednesday night, forcing customers to either hide in the store or frantically run for the doors.

Thornton police tweeted Wednesday night that they were responding to a shooting with "multiple parties down." They advised people to stay away from the area as dozens of police cruisers and emergency vehicles raced to the scene.

Aaron Stephens, 44, was in the self-checkout line when he heard a single shot followed by more bursts of gunfire, The Denver Post reported. He said customers started screaming and running for the exits.

"I was scared. I feared for my life," said Stephens, who has lived in Thornton for 20 years.

Meanwhile, Brandon Bonney said he received a call from his brother, who was inside the store.
